Description

The MAX98500EWE+T is an audio amplifier component belonging to the MAX985 series of micropower comparators. They have low-voltage operation, rail-to-rail inputs and outputs, and a wide operating voltage range, which makes them ideal for use in 3V and 5V systems. The component operates with dual supplies of ±1.25V to ±2.75V and has a quiescent supply current of 11µA while achieving a 300ns propagation delay. It is commonly used in portable/battery-powered systems, mobile communications, zero-crossing detectors, window comparators, level translators, threshold detectors/discriminators, ground/supply-sensing applications, IR receivers, and digital line receivers.

Specifications and features

• Operating voltage: 2.5V-5.5V
• Consumes only 11µA of supply current
• 300ns propagation delay
• Common-mode input voltage range extends 250mV beyond rails
• Push-pull output stage sinks and sources 8mA current (MAX985/MAX989/MAX993)
• Open-drain output voltage extends beyond VCC (MAX986/MAX990/MAX994)
• 80µA supply current at 1MHz switching frequency

Application Scenarios

The MAX98500EWE+T component is particularly useful in applications that require micropower comparators with low supply current and fast propagation delay, such as portable/battery-powered systems, mobile communications, and digital line receivers.
